摘要
利用模糊数学中异常从属函数方法对 1 990～ 1 997年华东地区 1 6种前兆观测方法 ,近 5万组观测数据的综合前兆场进行了时空演化特征研究。结果表明 ,异常从属函数 μ对发生在华东地区的 Ms≥ 5.0地震有较好的映震能力 ,可作为中期、中短期预报的综合指标 。
This paper studied the space-time evolution characteristics of East China with the method of improper slave function in fuzzy mathematics,which studied50 0 0 0 sets of comprehensive precursor field data observed by sixteen methods of precursory observation.Through the study,we can conclude that improper slave function shows fairly good earthquake-reflecting capacity to earthquakes with Ms 5.0 in eastern China, Which can be regarded as comprehensive parameter to the medium-term and short-term earthquake prediction and can determine three elements of an earthquake more exactly.
